I toyed with writing an extension method, also with inheriting from IList and implementing my own Sort() method birli well birli casting to a List but none of these seemed overly elegant.

Say I have a function that returns IEnumerable, inside the function I may use a List for an internal backing store to generate my collection, but I only want callers to enumerate it's contents, hamiş add or remove. Accepting an interface as a parameter communicates a similar message "I need a collection of strings, don't worry though, I won't change it."

It's more nuanced than that. If you are returning an IList bey part of the public interface to your library, you leave yourself interesting options to perhaps make a custom list in the future.

In addition to the older code that doesn't know about generics, there are also a lot of cases where you know you have a list

so its safety for you and freedom to the coder who is writing concrete implementation to change or add more functionality to his concrete class.

Inside the method, you should use var, instead of IList or List. When your data source changes to come from a method instead, your onlySomeInts method will survive.

Whether you return an Interface or a concrete type depends upon what you want to let your callers do with the object you created -- this is an API design decision, and there's no hard and fast rule. You have to weigh their ability to make full use of the object against their ability to easily use a portion of the objects functionality (and of course whether you WANT them to be making full use of the object).

You would because defining an IList or an ICollection would open up for other implementations of your interfaces.

If you're working within C# IList Kullanımı a single method (or even in a single class or assembly in some cases) and no one outside is going to see what you're doing, use the fullness of a List. But if you're interacting with outside code, like C# IList Nerelerde Kullanılıyor when you're returning a list from a method, then you only want to declare the interface without necessarily tying yourself to a specific implementation, especially if you have no control over who compiles against your code afterward.

This will help if you decide to change the implementation of your class later to use a different concrete class. In that case the users of your library won't need to update their code since the interface doesn't change.

Fakat list kullanımında kapasite belirtilmez kullanıcak veriler sınırlı ise örneğin haftanın günleri ise bunları diziye teşhismlayabiliriz ancak kullanılacak veriler araba plakası,telefon numarası gibi nüshası gizli veriler kullanıcak ise mutlaka C# IList Kullanımı list olarak saklanmalıdır.Şimdi C#’ta list tasarrufı derunin örneğimize bakalım.
